#include "ltwrappr.h"

L_INT LSegment::MrcSegmentBitmap(pBitmap, pSegOption)

LBitmapBase * pBitmap;	/* pointer to a bitmap handle */
pSEGMENTEXTOPTIONS pSegOption;	/* pointer to a structure */

Automatically segments the specified bitmap, finding the best segment combination without specifying minimum segment dimensions.

Parameter	Description
pBitmap	Pointer to the bitmap object that references the bitmap to be segmented.
pSegOption	Pointer to the SEGMENTEXTOPTIONS structure that controls the automatic segmentation process. This cannot be NULL.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Call this function to segment the bitmap automatically. LEAD will process the bitmap and break it into appropriate picture, grayscale, text and background segments.

Call the LSegment::MrcStartBitmapSegmentation function before using any of the segmentation functions. When the LSegment class object is no longer needed, free it by calling the LSegment::MrcStopBitmapSegmentation function.
